GOST-112821-80 PN16 Carbon Steel Welding Neck Flange introduction

GOST-112821-80 PN16 Carbon Steel Welding Neck Flange is designed to be joined to a piping system by butt welding, including lots of specification. The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement of the Welding Neck flange. The bore of Welding Neck flange matches bore of the pipeline, reducing turbulence and erosion.
